Problems solved by technology

[0002] Current thermal management technologies, such as natural cooling, wind cooling, liquid cooling (including oil cooling and water cooling) and other convective cooling methods, cannot efficiently cool backlight modules with high heat flux density due to the general heat dissipation efficiency of these cooling methods
For the current mechanical refrigeration device that uses a compressor for refrigeration, due to its relatively large volume, it cannot match the narrow frame panel
In addition, the heat generated by the light source components of the backlight module is easily wasted in the heat dissipation process.

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a light source assembly, a thermoelectric temperature control structure and a waste heat recovery structure. The thermoelectric temperature control structure includes a thermoelectric device. The waste heat recovery structure includes a phase change heat storage layer. A cold end of the thermoelectric device is in contact with the light source assembly and a hot end of the thermoelectric device is in contact with the phase change heat storage layer. Therefore, accurate temperature control and waste heat recycling of the light source assembly of the backlight module can be realized.

Description

【Technical field】 [0001] The present disclosure relates to the field of display technology, in particular to a backlight module and a display device. 【Background technique】 [0002] Current thermal management technologies, such as natural cooling, wind cooling, liquid cooling (including oil cooling and water cooling) and other convective cooling methods, cannot effectively cool backlight modules with high heat flux density due to the general heat dissipation efficiency of these cooling methods. For the current mechanical refrigeration device using a compressor for refrigeration, due to its relatively large volume, it cannot match the narrow frame panel. In addition, the heat generated by the light source components of the backlight module is easily wasted in the heat dissipation process. [0003] Therefore, there is a need to provide a backlight module and a display device to solve the problems in the prior art. 【Content of invention】 [0004] In order to solve the above...
